If you have never used braid for rigging, you are missing out! You can feel the transition between rock/sand, metal objects, shell beds, and just about everything. A good rod helps as well, looks like you got that covered!
For the past few years I have been using power pro 10#, right now I am experimenting with 832 6#. So far I love the 832 and it seems to be just as strong, if not stronger, than the PP. Time will tell!
For lindy rigging I put the walker and bead right on the braid, and then use a small barrel swivel and a 6# leader. Fluoro if its really clear, otherwise mono.
One warning, if you are dragging shell beds or dumped rock you will go through rigs like they are going out of style. Sharp rock (not natural river rock) and shells will eat that braid. But I don’t lindy over those types of bottoms anyways, I do 3-way with an 8-10″ dropper.
